openwebgis: The information tools (data base and GIS) to help paleontologists in their scientific researches

My article about OpenWebGIS and Paleobiology Database:

In modern scientific researches of biological direction the geographic information systems (GIS) are increasingly used. For example, GIS technology is successfully applied in the study of patterns of spatial and temporal distribution of biological objects with taking into account the unique features of the environment. Typically, a GIS is used for the analysis of current events and / or the future forecast, but they are also useful for the study of the fossils, living conditions in the distant past, changes in biodiversity and for determining historical patterns of biosphere evolution.

Convenience of GIS for integrated paleontological studies is due to the combination of database management systems functionality, editors of raster and vector graphics and a variety of analytical tools...

hi mate! as fellow paleontology enthusiasts!

i like to discuss about my theory: t-rex it's a superpredator that will attack anything they can! when they can! and whatever they can
my prove its: t-rex had a good vision like wolf, we knew they are predator
                   t-rex had a very similar brain to croc that prove my theory: they will attack whatever in front of them, and i've heard  the guy named greg erickson said that he have identified a triceratop's skull with a bite wounds from t-rex! and that bite wounds its recovered! THAT'S PROVE T-REX WAS A PREDATOR!
I hope there's paleontologist can give me more info for my theory

darksumomo: Cal Tech scientists measure body temperatures of 150 million year old dinosaurs

Cal Tech via physorg.com: Body temperatures of dinosaurs measured for the first time
by Marcus Woo
June 23, 2011
Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded. When dinosaurs were first discovered in the mid-19th century, paleontologists thought they were plodding beasts that had to rely on their environments to keep warm, like modern-day reptiles. But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T. rex depicted in the movie Jurassic Park, requiring warmer, regulated body temperatures like in mammals.

Now, a team of researchers led by the California Institute of Technology (Caltech) has developed a new approach to take body temperatures of dinosaurs for the first time, providing new insights into whether dinosaurs were cold or warm blooded. By analyzing isotopic concentrations in teeth of sauropods, the long-tailed, long-necked dinosaurs that were the biggest land animals to have ever lived—think Apatosaurus (also known as Brontosaurus)—the team found that the dinosaurs were about as warm as most modern mammals.

"This is like being able to stick a thermometer in an animal that has been extinct for 150 million years," says Robert Eagle, a postdoctoral scholar at Caltech and lead author on the paper to be published online in the June 23 issue of Science Express.

"The consensus was that no one would ever measure dinosaur body temperatures, that it's impossible to do," says John Eiler, a coauthor and the Robert P. Sharp Professor of Geology and professor of geochemistry. And yet, using a technique pioneered in Eiler's lab, the team did just that.

The researchers analyzed 11 teeth, dug up in Tanzania, Wyoming, and Oklahoma, that belonged to Brachiosaurus brancai and Camarasaurus. They found that the Brachiosaurus had a temperature of about 38.2 degrees Celsius (100.8 degrees Fahrenheit) and the Camarasaurus had one of about 35.7 degrees Celsius (96.3 degrees Fahrenheit), warmer than modern and extinct crocodiles and alligators but cooler than birds. The measurements are accurate to within one or two degrees, Celsius.Collapse )

Most dinosaurs formerly thought carnivorous may actually have been herbivores, according to a new study.

(The story linked persists in using the term 'vegetarians', which...I do not think it means what you think it means in this context, dear science reporter. But still worth a look.)

Mods, please delete this post if it's not appropriate.

Hello, fellow paleontologists. I just made a new community and I thought that it might be of interest to you.

skull_quiz is a weekly challenge where I will post a different skull every week, and then invite you to guess what it is. At the end of the week, I'll reveal the animal's secret identity. I'll be posting both extant and extinct forms, so keep your eyes peeled for the inevitable dinosaur. :)

I hope that it will be a fun way for people to share their cool skull pictures, learn a little bit of comparative anatomy, and just get some exposure to tetrapod diversity that they might not have seen. If it sounds like your kind of thing, please check us out, and take a guess on the week's featured creature.

darkslander: Hello Paleophiles.

Hello there fellow Paleontology enthusiasts,

My name is Nicholas and I reside on Cape Breton Island, Nova 
Scotia. I've been interested in Fossils and Paleontology related fields for many years but only recently have begun to collect and become more physical in my interests.

My collection is primarily made up of Upper Carboniferous flora, from my Island but I also have collected Devonian fossils from Kentucky and Indiana. Although I have no outstanding finds finds yet but I have been lucky in finding some excellent 
Calamites from my area.

I do also occasionally buy or trade fossils from trusted dealers and worldwide fossil friends, this collection is mostly made up of vertebrate fossils which due to my usual areas of hunting tend to not have this type.

Not to sound like a ad peddler but I am also an Administrator of a Fossil Forum, we have a lot of great information there and if anyone is interested in taking a look please feel free to pm me.

I look forward to reading what the other members of this community add and if anyone posts blogs on this subject matter regularly I would definitely like to read them if you would allow.

mexicanwine: gotta get me one.



Going, going, extinct.

A complete dinosaur skeleton will be sold at auction next month - a rare opportunity for New Yorkers to give their 21st-century habitats a little Jurassic decor.

The well-preserved dryosaur fossils, one of only two complete sets known to exist, are being sold by an anonymous private collector, said Josh Chait, director of the I.M. Chait Gallery.

"He got it straight from the paleontologists who discovered it in Wyoming in 1993," Chait said.

The 6-foot-tall dryosaurus, or "oak lizard," was a speedy herbivore with long, slender legs, a horny beak, heavy tail, and five-fingered hands that roamed the earth about 150 million years ago.

"The bones display a lovely soft, creamy coloring," according to the auction's catalog.

Although anyone is free to bid on the late-Jurassic dinosaur, only those with a lot of bones will be in the running, said Chait, who estimates the reptile remnants will sell for between $440,000 and $500,000.

"This is the largest and most complete skeleton we have ever sold," he said.

Well-heeled art collectors have in recent years been adding dinosaur fossils to their inventories.

"Not everyone is going to recognize a Monet or a Renoir when they visit, but everyone is going recognize the T-Rex skull on your wall right away," Chait said.

As for why the owner is parting with the dinosaur he's displayed in his home for 15 years, Chait said it's doubtful his decision had anything to do with the economic downturn.

"He is constantly getting new stuff, and maybe he has found a better specimen for that location," he said.

The only other dryosaur skeleton known to exist is on display at the Carnegie Museum of Natural History in Pittsburgh.

But according to Dr. Rod Scheetz of Brigham Young University, an authority on the Hipsilophodont family, of which the dryosaurus is a member, these fossils are superior.

It's "the best specimen I have ever seen," Scheetz said.

The March 21 auction also includes hundreds of other natural-history lots, including the skeleton of a wooly mammoth.

At 7 feet tall and 15 feet long, the mammoth is much more likely to end up in a Ripley's Believe it or Not than in a private home, Chait said.

laripop_3: Hello

Hello Paleophiles!
   I am Lari. I've been highly interested in paleontological studies since a young age. In the 7th and 8th grade I was part of the ONLY junior high level paleontology class in the United States. The class is held withing the walls of Lowell Junior High School located in Bisbee, Arizona. My old paleo teacher (no offense!) was none other than Heidi Johnson (Mrs. J to us students). She knows a great deal of other paleontologists. We even had the pleasure of meeting our paleontological hero (lol) Bob Bakker (thnx jmjoyce) at a convention in Tucson, Az. That was a historical moment in our young lives. Us students felt like we were meeting and shaking hands with a celebrity! We were even more shocked when we realized Mrs. J and Bob were friends!

   We collected fossils (once we found a huge ammonite outside Bisbee, Az on a paleo field trip!) and a vast aray of rocks and minerals. I literally have a couple of box fulls. From trilobites to dino dung, it's all great. So, I look forward to getting to know some of you fellow paleophiles!

Hello everyone!

I'm a palaeontology student in Portsmouth, UK. Recently I visited a locality in SW england called Aust cliff. It represents a marine transgression in the upper triassic (the rhaetian). There are several "bone beds" within the expose. The bone beds are known to contain fragmentary remains of marine reptiles, fish, and even dinosaurs.

On my trip I did indeed find some bone. Me and my tutor agree that the texture is reptilian, but cant seem to connect it to a particular animal, or shed much light on which part of the skeleton it may come from .

Here is a picture:

If anyone has any ideas I would be very pleased to hear them! Thanks

One observation that may not come across well in the photo is that it does appear to be rather thin....maybe no more that 5mm or so, although I will have to prepare it more to know exactly.

thanks again!

"This is an amazing discovery," Braddy said.

"We have known for some time that the fossil record yields monster millipedes, supersized scorpions, colossal cockroaches, and jumbo dragonflies," he added. "But we never realized, until now, just how big some of these ancient creepy-crawlies were."

Ummmm... what about Pterygotus? Hasn't it been known for years that eurypterids got really, really frickin' huge? There was one in Walking With Monsters, fer chrissakes. Or is that extra estimated 0.2 meters really REALLY shocking? "Never realized until now"? Huh??

Eh, science news for the general public. Gotta love it. ;)
